Product Series

MOAG means Manual Off-Axis Guider, a non-moving part of your optical train.


This smaller member of our off-axis guider product line is specifically designed to be integrated with SBIG adaptive optics (AO) devices, including the ST/AO8 and STL/AO-L systems. AO technology allows fast guiding that can dramatically lead to sharper stars and finer detail. The MOAG can also be used as a stand-alone guider for any camera. For stand-alone applications involving KAI11000XM and larger detectors, we recommended the MonsterMOAG or MegaMOAG.


  • Take full advantage of AO technology
  • Faster AO guiding for better resolution
  • Guide in front of your filters
  • More guide stars with unfiltered light
  • Guide in the main optical beam
  • Avoid differential flexture and cost of guide scope
  • Fixed guider position for automated data acquisition



  • MOAG-ST for SBIG ST/AO8 with T-thread adaptor
  • MOAG-A for SBIG STL/AOL with 2" STL adaptor
  • MOAG-S stand-alone with AP 2.7"-24 M/F adaptors
